Simple RC circuit with current source. Ddt e tRC Vc dt e tRC V s RC dt V s e tRC 1 RC dt The left side is the integral of the derivative of e tRC Vc so the integral resorts to e tRC Vc again. Lets assume the following waveforms for i t and v C t depicted below.
The above response is a combination of steady-state response ie. T is the elapsed time since the application of the supply voltage. Vs is the supply voltage.
I need the derivation to get this answer instead. V C t v C H t v C P t where v C H t is a homogeneous solution and v C P t is a particular solution. Directly write down the solutions.
Where v t is the capacitor voltage.
Develops ODEs in conjuction with PDEs and is aimed mainly toward applications. A separable linear ordinary differential equation of the first order must be homogeneous and has the general form where is some known functionWe may solve this by separation of variables moving the y terms to one side and the t terms to the other side Since the separation of variables in this case involves dividing by y we must check if the constant function y0 is a solution.
